2. kinetic energy: due to it being transferred through collisions
Answer: I think the answer is B. Potential energy
Explanation:
Because the higher the ball is held up the more energy it has.
I hoped I really helped out. ;)
Answer and Explanation:
NOTE: Magnetism means the magnetic property of a material that causes it to create a magnetic field, hence getting it attracted to a magnet.
EXPERIMENTAL PROCEDURE
1. Use a tape to attach a permanent magnet to the end of a ruler so that the magnet is facing away from the ruler. Don't cover the magnetic surface with the tape. ( Leave the magnet in its decorative casing.)
2. Place your metal objects in a row, and make predictions of which one of them will be attracted to the magnet and which will not.
3. Hold the magnet over each metals, and record which metals are attracted to the magnet. Go back over the
objects that were not affected by the magnet at least one more time to be sure you didn't miss any.
In this experiment, the independent variable is the magnetism of the magnet used. This is the independent variable because it remained unchanged and unaffected by the metals' magnetic properties all through the experiment.
While the dependent variable is the magnetism of the metals used. This is so because the magnetism of these metals varied and also because it is what is been measured in the experiment. Some were attracted to the magnet from very close range while others were attracted even at some centimeters away from the magnet which indicates that those metals have strong metallic properties.
<span>I believe this question has additional detail which stated
that during the 1st half, his speed was 2.01 m/s. From this we can
calculate his speed during the second half, v2, using the formula:</span>
v_ave = (v1 + v2) / 2
2.05 m/s = (2.01 m/s + v2) / 2
<span>v2 = 2.09 m/s</span>
